Command line argument question.

hello,
I have developed a class using NetBeans and i want to run it using command line , I've configured command line and it work correctly but my question is:
where this class should be stored to run it using command line arguments?
thanks........

where classes is the directory that contains the class files and org.mypackage.MyProgram is the fully-qualified name of the class that contains the main method, and arg0, arg1 etc. are the command line arguments.
